Measuring feed _VMS, fast measuring feed _SPEED[3]
Measurement is performed with the measuring feed of _VMS.
• If _VMS=0 and _FA=1: 150 mm/min
• If _VMS=0 and _FA>1: 300 mm/min
If _CHBIT[17]=1 and _FA>1 probing is performed twice. The fast measuring feed _SPEED[3]
is used for the first probing. After the probe has switched, it is retracted by 2 mm. This is
followed by actual measurement with the feedrate programmed in _VMS.
Measurement retraction velocity
Retraction from the measuring point is usually performed with the same speed (_SPEED[1],
[2]) or percentage of the rapid traverse as approach to the intermediate position (see above).
However, while collision monitoring (_CHBIT[2]=1) is active, it is possible with CHBIT[16]=1
to switch to the percentage of rapid traverse in _SPEED[0].
